Dataset Direct Download Service (WFS): Regulated zone of the natural risk prevention plan of Mont-Saxonnex (Haute-Savoie) — approved on 28 February 2017

For natural PPRs, the Environmental Code defines two categories of zones (L562-1): risk-exposed areas and areas that are not directly exposed to risks but where measures can be foreseen to avoid exacerbating the risk. Depending on the hazard level, each area is subject to an enforceable settlement. The regulations generally distinguish three types of zones: 1- ‘Building prohibited areas’, known as ‘red areas’, where the hazard level is high and the general rule is the prohibition on construction; 2- ‘prescribed areas’, known as ‘blue zones’, where the hazard level is average and the projects are subject to requirements adapted to the type of issue; 3- areas not directly exposed to risks but where constructions, works, developments or farms, agricultural, forestry, craft, commercial or industrial could aggravate risks or cause new ones, subject to prohibitions or requirements (cf. Article L562-1 of the Environmental Code). The latter category applies only to natural RPPs.针对自然风险防护分区（PPRs），《环境法典》第L562-1条划定了两类区域：风险暴露区域，以及虽未直接面临风险但可通过预先制定措施规避风险加剧的区域。 依据危险等级的不同，每类区域均需遵循可强制执行的管控要求。 相关法规通常将区域划分为三类： 1. 禁止建设区（俗称“红区”）：该区域危险等级偏高，通用准则为严禁开展建设活动； 2. 管控建设区（俗称“蓝区”）：该区域危险等级中等，建设项目需遵循适配风险类型的管控要求； 3. 间接风险区域：此类区域未直接面临风险，但农业、林业、手工业、商业、工业类的建设、工程、开发活动或农场运营可能加剧既有风险或引发新风险，需遵守相应的禁止条款或管控要求（详见《环境法典》第L562-1条）。 上述第三类区域仅适用于自然风险防护分区（RPPs）。
